a corporation of Wisconsin 'appuaonmy 5, i930. semi No. uaszo '4 claims.w1.' 15s- 115)- My invention relates to lighting devices, particularlyof the type employed in connection with gas ranges for lighting theburners thereof, and contemplates an improved construction, wherein,

5 the hood of the torch head is formed as a unit with or integral `partof the grate of the gas range.

More particularly uw invention relates to the type of torch head adaptedfor use with gases having relatively high heating or B. t. u. values lin which the torch head is provided with a flame projecting arrangementfor preventing the lighting flame or iiames from curving or risingupwardly away from and missing theburners.

My invention is illustrated in the accompanying drawing, in which:

Figure 1 is a fragmentary perspective view' of a gas range showing anembodiment of the present invention therein;

Figure 2 is a bottom plan view of the grate 20 structure and torch headarrangement;

Figure 3 is a vertical detail section taken on the line 3-3.of Figure 2;Y

Figure 4 is a fragmentary vertical detail section taken on the line4-40f Figure 2;

Figure 5 is .a fragmentary perspective view showing another form oflighter hood with the grate broken away and partially in section; and

Figure 6 is a side elevational view of another form of hood again withthe grate broken away and partially in section.

The gas range is illustrated at 5. It is provided with a grate 6overlying the burners 7 and removably supported marginally at 8 upon amarginal ledge or other supporting means alongl the inner margin of theframe 9 in the manner of existing grate arrangements, of which theparticular grate shown is illustrative.

The usual existing stringer pipe 10 supplies fuel to the burners 7, andthe burner fuel supply connections are individually controlled by burnercontrol valves 11 in the usual or any vsuitable manner.

The grate 6 shown is of sectionalized and specically two-partconstruction divided at 12 and -comprising a pair of grate sections 13,each provided with a generally rectangular frame 14, in each of whichframes 14 is a front and a rear arrangement of grate bars 15 and 16formed as an integral or unitary vpart of the frames 14 and pipe or gasmanifold 10, and adjacent the connection is a valve 18 of the type inwhich a restricted-by-pass for the gas maintains a small pilot flame latthe-lighter tip 19 of the torch head, andin which depression of theexternal button 20, manually, eiects the iiow of a considerablyincreased amount of gas in order to project the flame to the burnerwhich it isintended to light.

The lighter tip 19 is mounted upon the `u'pturned outer end 21 of thelighter tube 17, andvwhen the parts are brought into operative relation,as shown in Figure 1, takes position within the hood 22.

The.hood22 is formed as an integral unitary part of the grate 6, beingdivided in the particular grate arrangement shown alongthe line ofdivision 12 between the grate sections 13 with onehalf 22a of the hoodformed as an integral unitary part of one grate section 13, and theother half 22b of the hood formed as an integral unitary part of theother grate section 13. When thegrate sections 13 are mounted in theframe 9, the bringing of the sections of the grateinto operativerelation for use also brings the two hood parts together, and in suchrelation as to complete the hood, forming, in eiect, a substan- ,tiallyunitary enclosure for the lighter tip 19.

The hood 22 is open at the bottom and may have an opening 23 at the topformed by complementary opening portions in the upper wall portion 24 ofthe hood parts.

Each of the hood parts 22a and .22h has openings 25 through which thelighting ames are projected to the burners 7, vand a pair of flameprojecting arrangements, one for each of the two burners on thecorresponding side of the range, these iiame projecting arrangementscomprising, in this particular embodiment, inverted channels 26 formedat their torchhead ends as an integral unitary part of the correspondinghood parts 22a, 22h. The inverted channels extend outwardly from thehood over the top of. the lighting flames and form obstructions forpreventing the outer ends of the lighting flames from curving or risingupwardly and missing the burner when a gas of high caloriiic or B. t. u.valuel is employed, and by a gas of high calorific or B. t. u. value, Imean a gas with a caloric or B. t. u. value higher than heretoforelsuccessfully employed with lighters of this sort, and more specifically,a gas such as described in the covpending application of OscarJ.'Lein's, Case 11,

* In Figure 5 the hood instead of being divided wholly along the line ofdivision 12 between the grate sections 13', has a portion along the topof eech side overhsnging the sdjecent 'portion .of the other side et 28.This forms on the hood v 42 e vertical interlock for the grote motions13',

it being understood that Where this verticel interlock is not wformed onthe hood the interlock roer oe formed on the grote sectionsindependently oi the hood, es is now commonly done where the hood isseperate from the grate, or where there is no lighter et alL ln Figure 6the flame projecting errengement instead of comprising inverted channelstermed es en integral unitary port oi the hood, comprises tiices 39,which may ce formed ci sheet metel, or the like, end which ore mountedin openings in the Walls of the hood sections 32e, 32o. The tubes 30 ereshown es being slit longitudinelly along the bottom, but it is to beunderstood that the openings et the bottoms oi the tubes met' ce ciother form than the longitudinal slits i3d, es shown.
